IMPROV EMENT lN DELlNEATlNG-TELEGRAPHS.

Specification forming art of Letters Patent No. 37,33 I, dated January 6, 1863.

' To all whom it may concern :Be it known that I, Chevalier GAiiTAN BONELLI, of Milan, in the Kingdom of Sar dini-a, engineer, have invented Improvements in Electrical Typography and Autography to be used for. Transmitting Telegraphic Dispatches; and 1 do hereby declare that the followingis a ful clear, and exact description of the same.

My invention consists in repi od ucin g immediately, at indefinite distances, one or more lines of types or handwriting delineated by an insulating-ink onmctallic paper.

The principle upon which saidinvention is grounded is the use of a number of conductors sufiicient for acting atonce upon thewhole extent of the typesto be reproduced, such conductors meeting at both ends of the line or range with a comb having its teeth close to each other and insulated between each other. The types or handwriting being laid on a plati'orm and being set in communication with a batter said'platform comes by a regular motion and passes under the comb, causing it thereby to touch on its passage the types or handwriting. Theelectricalcurrent,on passing only through the combs teeth which are in contact with the metallicsuri-aces, is, through the corresponding conductors, carried on to the opposite stationpvhere the comb is in contact with a chemical papenwh-ich becomes discolored on the passage of the electric fluid. The paper being thus laid on a platform which has nearly the same motion as that-of the expediting-station, reproduces the types, handwriting, signs, or drawings which are passing under the comb. I a

I shall now describe thesmall 'apparatus constructed according to the principles of my invention, as represented in the annexed drawing; but 1 do not confine myself to the particular construction herein described and shown, this being merely intended as one specimen.

Figure 1 shows a vertical section through 1 2 of the whole telegraphic system. Fig. 2

shows the plan, and Fig. 3 an end view, of the same apparatus.

In these figures thesame letters and figures of reference indicate the like parts where they recur.

a is the table or frame supporting the whole apparatus; J1, cast-iron socket, fixed to the frame by means of screws 0; d d, beveled metal rulers, serving as guides for the sliding of the carriage: 9, slot cut through the socket b,intended for the passage of com posing-stick or frame containing the types the picture of which is to be reproduced; j, second slot, admitting a spiral spring or coiled-wire coudoctor.

9 is the carriage, sliding between the slidehars d d. In this carriageare fitted the composing-frame :containing the types and the receiver on which is applied the paper coated over with a chemical preparation.

It is the composing-frame, fitted on the carriage gand containing the type; 5, common type, setprojectin g, as usual; j, metallic spaces placed between each type.

7c is the metallic plate or receiver, screwed upon the carriage and insulated therefrom by two small ivory blocks, Z I. On said plate is applied the chemical paper, which is to be acted upon by the teeth of the receiving-comb being brought in contact therewith.

m is ascrew fastened on the socket, serving to controland confine the course of the carriage in, iron ruler, guided by two supports, 0 0', between which it slides with the least possilc friction; p, cramp screwed upon the car riage g on one side, and on the other embracing the iron ruler a tightly enough to allow of the said'ruler being carried away while the carriage is moving; (1 q, screws engaged on ruler n, on each side of the support 0, and serving to confine its course; 0' r, vertical upright, fixed on table a by means of screws .9 s, and supporting the upper parts of the appa ratus; t, ivory insulator, (being a joint part of the vertical support,) upon which are placed the electric contact-blocks a, to each of which comes a wire from each of the two combs, in order to'establish the current; "0, rotation-axes, round which turn the combs.

war are socket-levers, upon which are screwed two ivory plates, 3 Between these plates are engaged the ends of the conducting-wires, in order to form the teeth 2 z of the manipulating and the receiving combs, one of which being brought in contact with the types 2', and the other with the chemical paper which is applied onto the receiver 7c, the two combs being independent from one another. The lever to, which supports the comb of the receiver, is provided with an ivory insulator, 1, which lifts the comb off the composing-frame when the comb of the receiverislifted, which,

as already said, carries the ivory insulator 1.

2 represents screws fastened to each of the combs for the purposeof raising or lowering the teeth of the same above the types 71 or receiver k, and thus compensating for the wearout of the said. teeth.

3 represents a lifter screwed upon the iron ruler it, intended to raise up the combs when the carriage, after having moved for the reception and sending out of dispatches, turns back to take its former position again, then the said lifter 3 permits of the combs dropping down again, so that they may act upon the types and the paper, coated over, as before said, with achem-ical preparation, when the carriage moves forth in order to receive or send out a dispatch.

4: represents-screW-blocks in which the conducting-wires are fitted \5 5, wires connected to the two screw-blocks 4; 6, spring or coiled wire, already mentioned, serving as an electric conductor by connecting, through the bracket 7, the wire 5 to the receiver k.

8 is a knobscrewedto and serving to operate the carriage g, which leads under the twin combs, the manipulator and receiver. Said knob,"which is operated by hand, may be replaced by a strap, a chain, a counter-weight,

or any suitable clock-work by which the car riage has imparted to ita regular, uniform motion under the combs while a dispatch is sent out or received. An electric current actuates at once the two platforms, which require placed on the poles, as is actually done, are contained in a small cable laid on the same poles. Said cable, which is intended to diminish the sion and reception at once.

To adapt my invention to the reproduction of handwriting delineated by an insulating ink or varnish upon metallic paper, (tin-foil,) the said paper, with the writing upon it,-is placed in the position occupied by the type-case h.

I do not claim as having beenvfirst invented by me the use of anumber of wires, whether more or less, considered by itself, for transmitting, recording, or delineating by means of electricity or electromagnetic Power letters, figures, or outlines; but

WhatI claim as myinvention, and desire to secure by Letters Patent, is-

The employment, for producing the image of types or handwriting, of anumber of conducting-wires when combined with two series of. flexible comb-like metallic teeth or electric conductors arranged nearly close together but insulated from each other, and with a movable platform or platforms carrying the conductin gtypes or handwritingand the chemically-prepared paper on which the image is to be produced, the whole operating substantially as hereinspecified' GAETAN BONELLI'.
